Abstract

An image processing device includes calculation means for acquiring information including a defocus range of a captured image from storage means in which information including the defocus range of the captured image is stored as incidental information of the captured image, and calculating a focal ratio of the captured image based on the information including the defocus range, and display control means for performing display control of the captured image based on the focal ratio.

         1 . An image processing device comprising:
 calculation means for acquiring information including a defocus range of a captured image from storage means in which information including the defocus range of the captured image is stored as incidental information of the captured image, and calculating a focal ratio of the captured image based on the information including the defocus range; and   display control means for performing display control of the captured image based on the focal ratio.   
     
     
         2 . The image processing device according to  claim 1 , wherein
 the defocus range of the captured image is a defocus range of an entire subject in the captured image, which is estimated using a defocus range estimation model.   
     
     
         3 . The image processing device according to  claim 1 , wherein
 the calculation means calculates the focal ratio according to the defocus range of the entire subject in the captured image.   
     
     
         4 . The image processing device according to  claim 1 , wherein
 the calculation means calculates the focal ratio based on the defocus range and a depth-of-field of the captured image.   
     
     
         5 . The image processing device according to  claim 1 , wherein
 the display control means displays the focal ratio on display means in association with the captured image.   
     
     
         6 . The image processing device according to  claim 1 , the image processing device further comprising:
 display order determination means for determining the display order of the captured images based on the focal ratio, wherein   the display control means displays the captured images on the display means based on the determined display order.   
     
     
         7 . The image processing device according to  claim 1 , the image processing device further comprising:
 selection means for selecting the captured images to be displayed on the display means based on the focal ratio.   
     
     
         8 . The image processing device according to  claim 1 , the image processing device further comprising:
 selection means for selecting the captured images to be displayed on the display means based on the focal ratio and a predetermined threshold value.   
     
     
         9 . The image processing device according to  claim 1 , wherein
 the defocus range of the captured image is estimated from the defocus range estimated from a live view image and a lens drive amount for AF control.   
     
     
         10 . The image processing device according to  claim 1 , wherein
 the defocus range of the captured image is estimated for each area of the subject.   
     
     
         11 . The image processing device according to  claim 9 , wherein
 the storage means stores the defocus range estimated from the live view image and the lens drive amount as incidental information of the captured image, as information including the defocus range of the captured image.   
     
     
         12 . The image processing device according to  claim 1 , the image processing device further comprising:
 selection means for selecting the captured images to be displayed on the display means based on the focal ratio corresponding to the area of the subject selected from an input device.   
     
     
         13 . An image processing method comprising:
 acquiring information including a defocus range of a captured image from storage means in which information including the defocus range of the captured image is stored as incidental information of the captured image, and calculating a focal ratio of the captured image based on the information including the defocus range; and   performing display control of the captured image based on the calculated focal ratio.   
     
     
         14 . A non-transitory computer-readable storage medium configured to store a computer program comprising instructions for executing following processes:
 acquiring information including a defocus range of a captured image from storage means in which information including the defocus range of the captured image is stored as incidental information of the captured image, and calculating a focal ratio of the captured image based on the information including the defocus range; and   performing display control of the captured image based on the focal ratio.   
     
     
         15 . An image processing device comprising:
 acquisition means for estimating a defocus range of a captured image and acquiring the estimated result as defocus range information; and   focal ratio calculation means for calculating a focal ratio of the captured image based on the defocus range information acquired by the acquisition means.   
     
     
         16 . An image processing method comprising:
 estimating a defocus range of a captured image and acquiring the estimated result as defocus range information; and   calculating a focal ratio of the captured image based on the defocus range information acquired in the acquisition process.
